Hello,
I’m having a hard time finding beam span information I can use.
I am building a porch on the 24′ gable end of my house. The 4/12 shed rafters will sit on a header 8′ out from the house and continue past for 2′. so 240 sq feet of roof w/ a 60lb snow load.
I would like to set it on three posts w/ 12′ spans but am not sure how big a solid Doug fir or built up syp beam would have to be. And if I break it into three 8′ spans how much shallower could I make the beam?
Any help would be appreciated.
